Definitions

  • the invention relates to the field of high voltage switch technology. It relates to a high power switch and a method for protecting a hot gas and / or gas pressure sensitive element of a high power switch from a hot gas flow according to the preamble of the independent claims.
  • Arc-extinguishing high-power switches are known from the prior art.
  • a flow of gas heated by the arc quenching gas, typically SF 6
  • Such hot gas flow can create significant pressures and, if it encounters a hot gas and / or gas sensitive element that may be present in the high power switch, can damage or destroy such. Damage or destruction of a such element can lead to malfunction of the high-power switch to failure.
  • the arc contact tube is movable via mounted sliding seals along the switching chamber axis. During the switch-off process, the arc contact tube separates from the burn-off pin and the extinguishing gas can expand from the high-pressure reservoir via a blow valve in the switch.
  • the high-performance switch according to the invention in which a hot gas flow can form as a result of an electric arc burning during a switching operation, has a hot-gas and / or gas pressure-sensitive element and a seal is provided to protect the element from the hot gas flow and is characterized in that the seal a partial flow generating means for generating a partial hot gas flow of the hot gas flow and, downstream of this, a mass flow reducing agent for reducing the Mass flow of the partial hot gas flow and an expansion means for volume expansion of the partial hot gas flow on.
  • the hot gas flow can be reduced in pressure and / or temperature, so that the element is protected from damage by the hot gas flow.
  • Pressures and temperatures that are present in hot gas flows may be greater than 10 bar and greater than 20 bar or above 1500 K and above 2000 K.
  • Such a seal has the advantage that the mass flow reducing agent can produce a reduced pressure compared with the pressure of the hot gas flow, resulting in a reduced pressure loading of the element, and the expander can achieve a reduction in the temperature of the partial hot gas flow compared to the temperature of the hot gas flow become.
  • the mass flow reducing agent can produce a reduced pressure compared with the pressure of the hot gas flow, resulting in a reduced pressure loading of the element, and the expander can achieve a reduction in the temperature of the partial hot gas flow compared to the temperature of the hot gas flow become.
  • the expansion medium is arranged downstream of the mass flow reducing agent.
  • a partial hot-gas flow reduced in pressure by the mass flow reducing agent is reduced in its temperature by expansion in the expansion medium.
  • it may also be the mass flow reducing agent downstream of the expansion means.
  • the seal achieved by the cooling and pressure reduction, a movable non-contact seal. This makes it possible to protect elements that interact with moving parts of the high power switch.
  • a seal is arranged to protect a hot gas and / or gas pressure sensitive element of a high power switch from hot gas flow between the hot gas flow and the element, and a partial hot gas flow is coupled out of the hot gas flow in the seal, the mass flow of the partial hot gas flow is reduced and the Partial hot gas flow expands in terms of volume.
  • the mass flow of the partial hot gas flow is caused substantially by the generation of internal friction within the partial hot gas flow. This is done advantageously by the partial hot gas flow is presented to a flow-through cross-section, which is small. In this way, the mass flow reduction is realized in a simple way. Further, this provides the advantage that parts of the high power switch adjacent to the mass flow reducer can receive heat from the partial hot gas flow so that the mass flow reducer also acts as a means for reducing the temperature of the partial hot gas flow.
  • the partial flow-generating means has a gap or is merely a gap.
  • the gap can also be part of the Be mass flow reducer or the expansion agent. In this way, the partial flow generating means is realized in a simple way.
  • the mass flow reducing agent has a channel.
  • a channel is advantageously elongate and advantageously narrow.
  • the channel can be extended along an axis and, in an advantageous embodiment, can be designed as an annular channel.
  • the partial flow generating means may also be integrated in the expansion medium or in the mass flow reducing agent.
  • the mass flow reducing means may be formed as a duct and the partial flow generating means as the hot gas flow side end of the duct.
  • the expansion means has a pressure relief space open to the element or is formed by such.
  • the pressure relief space is used in its function only the pressure relief, ie there are no other elements such.
  • the partial hot-gas flow is presented with an increasing cross-sectional area upon entry into the expansion means.
  • the partial flow producing means or Mass flow reducing agent flows through the partial hot-gas flow through a cross-sectional area of a certain size, and the partial hot gas flow in the expansion medium presented cross-sectional area is greater than this.
  • the expansion means at least one pressure relief opening, through which the expansion means is connected to a reservoir volume containing gas whose temperature is at most as high as the temperature of the hot gas flow and / or its pressure is at most as high as the pressure of the hot gas flow.
  • the temperature and / or pressure in the reservoir volume is less than the temperature and pressure in the hot gas flow.
  • the element can also have a combined function. For example, it may simultaneously act as a guide and have a sealing function.
  • a seal according to the invention can be used in the case of very high relative speeds between such first and second parts of the heavy-duty circuit breaker; For example, if at least one of the parts is coupled to the drive motion for switching the switch, in which case relative speeds of over 10 m / s and over 15 m / s may occur between the first and second parts.
  • the first part of the high power switch may be at least partially extending along an axis.
  • the mass flow reducing agent can be extended along an axis.
  • the mass flow reducing agent and / or the expansion agent are adjacent to the first part.
  • a holder for holding the element. This can advantageously contribute at least partially to the formation of a further channel connecting the element to the expansion means (pressure relief space).
  • a holder for holding the element is provided, which is formed integrally with the seal together. This simplifies the manufacture of these high-performance switch components and can ensure a defined fixed arrangement of these high-performance switch components.
  • a seal having a partial flow generating means and, downstream thereof, a mass flow reducing agent and an expanding agent.
  • a gasket may be used in a high power switch or in any other device in which hot gas flows occur and an element is to be protected from such hot gas flow.
  • Advantageous embodiments are possible in the manner described above.
  • Fig. 1 shows schematically and in section a detail of a substantially rotationally symmetrical high-power switch with an axis A.
  • An outflow pipe 30 which is movable relative to a second part 40 of the high-power switch along the axis A, by a hot gas flow 8 (symbolized by arrows) flows through. Through an opening 31, the hot gas can flow out of the outflow pipe.
  • a guide 10 arranged outside the outflow pipe 30 is provided, for example a hollow cylindrical piece of PTFE with additives or another polymer. The guide is held in a holder 11.
  • seal 1 is provided between the opening 31 and the guide 10, which is formed in a sealing body 1 a.
  • the seal 1 has a longitudinally extending and formed due to the rotational symmetry as an annular channel channel 2, through which the hot gas flow 8 facing end 2a, a partial hot gas flow 8a from the hot gas flow 8 is separated.
  • the partial hot-gas flow 8a flows through the narrow channel 2 and enters a pressure-relief space 3, which adjacent to the channel 2 has an optional funnel-shaped opening of the pressure relief space 3.
  • the flow rate of the partial hot gas flow 8a is limited by the sonic velocity of the hot gas, and because of the small cross section available to the partial hot gas flow 8a in the passage 2, there is considerable internal friction in the gas of the partial hot gas flow 8a. As a result, the mass flow of the partial hot gas flow 8a in the channel 2 is considerably reduced. At the pressure relief chamber-side end of the channel 2, a hot gas pressure which is significantly reduced compared with the hot gas pressure of the hot gas flow 8 is thus present.
  • the mass of the pressure reduction of the partial hot-gas flow 8a caused by the channel 2 can be achieved.
  • a further effect is that, due to the contact of the partial hot-gas flow 8a with the sealing body 1a and the outflow pipe 30, which both delimit the channel 2 and generally have a significantly lower temperature than the partial hot-gas flow 8a, the temperature of the part -Heissgasströmung 8a is reduced.
  • This effect can also be varied by varying the length of the channel 2 and its cross section.
  • the transition from the channel 2 to the pressure relief space 3 of the partial hot gas flow 8a is an enlarged to be flowed through Cross-sectional area available (for example, with continuously increasing cross-section, as in the illustrated in the figure subspace 3a.).
  • the hot gas is expanded. Due to the expansion of the hot gas in the pressure relief chamber 3, there is a cooling of the hot gas.
  • the reduction in the temperature of the hot gas can be varied by varying the volume of the pressure relief space 3 and / or the cross-sectional area increase in the transition from channel 2 to the pressure relief space 3.
  • the pressure relief chamber 3 is connected to the guide 10.
  • Another function of the subspace 3a is to widen or fan out the flow profile of the part-hot-gas flow emerging from the channel 2, so that a lower pressure is exerted on the further channel 5 opposite the channel 2 than would be the case without the sub-space 3a ,
  • the guide 10 is exposed to a lower pressure of hot gas of lower temperature than would be the case in the hot gas flow 8.
  • the seal 1 does not touch the discharge pipe 30 and is insofar a non-contact seal. It is therefore in the case of very large relative speeds between parts 30,40 usable.
  • At least one pressure relief opening 4 is provided, through which the Pressure relief chamber 3 is connected to a serving as a reservoir volume 20 exhaust volume 20.
  • the space in which the hot gas flow 8 impinges on the channel 2 can be completely separated from the reservoir volume 20 or connected to it via a more or less large opening. A stronger separation allows a greater pressure drop from the pressure relief chamber 3 to the reservoir volume 20, so that the pressure relief opening 4 can be effective even at lower pressures.
  • the seal 1 can also cause less hot gas and thus less contaminants to the seal 1 and in a space 90 arranged beyond the seal 1 reach. This may be particularly important if in this space 90 electrically insulating parts form a Isolierrange, over which it could come in the case of contamination of the insulating parts to flashovers and corresponding switch malfunction.
  • the guide 10 also has a sealing effect.
  • the seal especially by the choice of their dimensions, dimensioned so that on the one hand, the temperature to which the element 10 to be protected (guide) is exposed, is so low that it is not damaged, and on the other hand, the pressure, which Guide 10 is exposed, so low that the guide 10 has a sufficient sealing effect for the underlying space 90.
  • the sealing body 1 a (at least in the region of the channel 2) made of a temperature-resistant material such as ceramic, tungsten, tungsten carbide or steel.
  • Fig. 2 shows a larger section of a high-performance switch in the open state, which is similar to the structure in Fig. 1 illustrated high-performance switch.
  • the seal 1 is integrally formed in this case with the part 40 of the heavy-duty circuit breaker.
  • the high-power switch also has a first arcing contact piece 51 and a second arcing contact piece 52, between which an arc 50 burns for a few milliseconds to a few tens or even a few milliseconds during a turn-off operation.
  • the contact piece 51 is surrounded by an auxiliary nozzle 55.
  • a main nozzle 56 forms with the auxiliary nozzle a connection of the arc space to a heating volume 80, which receives a portion of heated by the arc 50 gas. Another part of the heated gas flows in the direction away from the second contact piece 52 through the outflow pipe 30.
  • a boiler 22 limits a mixing volume 21, in which the hot gas of the hot gas flow 8 can mix with cooler, clean gas.
  • the space bounded by the boiler 22 may also be referred to as the flow-in space 21, since it also has the function of limiting the space in which the hot gas flow 8 flowing in against the seal 1 is present.
  • Through an opening 24 is the Mixing volume 21 connected to the reservoir volume 20.
  • pressure (and also temperature) in the reservoir volume 20 can be kept smaller than in the mixing volume 21 at least for a certain period of time. This favors the pressure-limiting effect of the pressure relief opening (s) 4 for the pressure relief space third
  • the discharge pipe 30 is coupled by means of a hinge 71 to an insulating rod 70, which in turn is connected to a drive, not shown.
  • the guide 10 ensures a linear, along the axis A directed movement of the discharge pipe 30, while the insulating rod 70 performs an angular movement in a plane A containing the axis.
  • the guide 10 also has a sealing function intended to prevent the penetration of hot gas into the space 90, so that no flashovers occur in the field-loaded area near the insulating rod. Such flashovers may be favored by adsorption of impurities present in the hot gas on the surface of the insulating rod 70 as well as lack of dielectric strength of the gas present in the region of the insulating rod (pressure, temperature, impurities).
  • the hot gas flow 8 is essentially caused by a pressure surge and thus of a correspondingly short duration.
  • the seal 1 is particularly well suited.
  • Fig. 3 shows schematically and in section a further embodiment of the invention.
  • a hot gas flow 8 to be protected element 10 either a seal 10 or a contacting element 10 is provided.
  • the FIG. 3 is interpretable in at least these two ways.
  • It is a bushing 30 'is shown, which may be part of a high-power switch, but also in other devices, such as other high-voltage devices may be provided.
  • the part 30 ' may for example also be a preferably movable contact piece of a high-power switch. In this case, the part 30 'does not necessarily require insulation as shown in FIG Fig. 3 is provided on the part 30 '.
  • the contacting element 10 may, for example, comprise contact blades.
  • the seal 1 in the case of a switch with two movable contact pieces, such as an arcing contact piece 30 'and a (in Fig. 3 not shown) contact tulip.
  • the movable contacting element 10 is then protected from the hot gas flow generated by an arc resting on the arcing contact 30 '.
  • the mutual mobility of the two parts 30, 40 '(or 30, 40) does not have to be a linear mobility, but may, for example, also be a turnability or simply be a mutual mobility in terms of play or adjustability.
  • the element 10 is a seal
  • this may for example be made of a polymer and prevent penetration of gas or liquid into the region of the hot gas flow 8 and / or the escape of hot gas of the hot gas flow 8.
  • the seal 1 is provided, which is constructed substantially the same and has the same functional principle as in Fig. 1 shown.
  • the element 10 is a contacting element 10
  • it may for example be a multi-contact ring 10 or a spiral spring contact element 10 and serve to establish a releasable electrical contact between the (electrical) feedthrough 30 'and the second part 40.
  • the seal 1 has substantially the same structure and the same principle of operation as in Fig. 1 shown.
  • Protection of hot gas flow through the seal may be understood to reduce the temperature and / or pressure of a gas through the seal.
  • the hot gas flow may be continuous or, as in connection with the Fig. 1 and 2 described embodiments in the case of a heavy-duty switch, short-lived and pressure shock-like.
  • pressures of typically 10 bar to 25 bar and temperatures of 1000 K to 2500 K are typically present for 10 ms to 200 ms as a result of the hot gas pressure surge.
  • pressures of typically 10 bar to 25 bar and temperatures of 1000 K to 2500 K are typically present for 10 ms to 200 ms as a result of the hot gas pressure surge.
  • other applications of the seal also smaller and larger pressures and temperatures are conceivable.
  • the gasket of the present invention may also be referred to as a high-pressure gas protection device, a high-temperature gas protection device or a high-pressure gas high-temperature gas protection device; or as a protective device against high-pressure gas pulses or as a protective device against gas pulses, in particular high-pressure gas pulses of high temperature.
